Technical and economic feasibility of the capture and geological storage of CO2 from a bio-fuel distillery: CPER Artenay project

AbstractThis paper first focuses on the environmental benefits of the CCS system applied to a bio-ethanol distillery before estimating its feasibility under geological and economic constraints.First, the calculation of CO2 balance in this application shows that the introduction of CO2 capture and sto rage in biomass energy systems (B-CCS) can si gnificantly increase the CO2 abat ement potential of the system and even leads to negative carbon emissions. Besides, a preliminary geological investigation reveals that the studied area has a good storage potential although the presence of major faults, while the low capture costs of CO2 from biomass fermentation emphasize the economic potential o f such a solution

A site selection methodology for CO2 underground storage in deep saline aquifers: case of the Paris Basin

International audienceSite selection is a fundamental step, which can condition the success of a CO2 geological storage. A CO2 storage has to gather several targets, which can be expressed through a list of criteria. In the proposed site selection methodology, these criteria can be classified into “killer criteria” and “site-qualification criteria”, whose combinations allow identifying potential sites and the most appropriate one(s). This multicriteria methodology is applied on the PICOREF study area, located in the Paris Basin, on which potential site(s) in deep saline aquifers are investigated

METSTOR: A GIS to look for potential CO2 storage zones in France

International audienceThe METSTOR project offers a methodology to look for potentially interesting CO2 storage areas in France at the initial stage, before the "site selection" step. Our tool, embodied in a Geographic Information System, is based on an interactive map of CO2 storage capacities. Other relevant information layers are included. The geographic layers are complemented with a series of online technical notices. It seems to be the first open online GIS that offers policy makers, businesses and the public at large an integrated access to that necessary information. Our prototype, limited mainly to the Paris Basin, is released online at www.metstor.fr

A multidisciplinary study of a syntectonic pluton close to a major lithospheric-scale fault: relationships between the Montmarault granitic massif and the Sillon Houiller Fault in the Variscan French Massif Central. Part II: Gravity, aeromagnetic investigations and 3D geologic modeling.

International audienceNew gravity and aeromagnetic investigations have been carried out to understand the emplacement mechanisms of a granitic pluton and the relationships with a nearby lithospheric-scale fault. This paper concerns the second part of a methodological multidisciplinary study and complements previous geochronologic and Anisotropy of Magnetic Susceptibility (AMS) studies on the same pluton. In the northern part of the Variscan French Massif Central (FMC), the Montmarault massif crops out along the Sillon Houiller Fault (SHF). Bouguer and aeromagnetic anomaly maps imply thickening of the pluton along the SHF and suggest laccolitic spreading northwestwards. Based on petrophysical measurements, direct 2D joint gravity and magnetic modeling has been performed along 10 cross-sections. In order to quantitatively constrain the 3D pluton geometry and its relationships with surrounding geologic units, these geophysical cross-sections, new structural information (field and AMS measurements) and petrophysical data have been integrated into a regional 3D geological and geophysical model. Altogether, the results obtained from geochronology, petro-magnetic fabrics (Part I), gravity and aeromagnetic investigations as well as 3D modeling (Part II), demonstrate that the Montmarault pluton was emplaced during the Namurian period along the SHF. Our results further show that, at that time, in response to a NW-SE regional extension, if the SHF existed, it behaved as a normal fault. Mylonites attesting for synmagmatic normal motion on the northeastern part of the Montmarault pluton strengthen this tectonic scheme. During the Late Carboniferous, the FMC experienced NE-SW extension along the SHF by 80 km of brittle left lateral wrench offset. This second tectonic event is well recorded in the Stephanian coal basins which were formed along NW- SE listric brittle faults and constrain the present-day shape of the Montmarault pluton

Late orogenic carboniferous extensions in the Variscan French Massif Central

International audienceThe Variscan French Massif Central experienced two successive stages of extension from Middle Carboniferous to Early Permian. In the northern Massif Central, the first stage began in the late Visean, immediately after nappe stacking, and is well recorded by Namurian-Westphalian synkinematic plutonism. The Middle Carboniferous leucogranites widespread in the NW Massif Central (Limousin and Sioule area) were emplaced within a crust extending along a NE-SW direction. At the same time, the hanging wall or "Guéret extensional allochton" moved toward the SE. Several examples of the synextensional plutonism are also recognized in central Limousin: Saint Mathieu dome, La Porcherie, and Cornil leucogranites. These examples illustrate the relationship between granite emplacement and crustal scale deformation characterized by NW-SE stretching and NE-SW shortening. In the central and southern Massif Central (Cévennes, Châtaigneraie, and Margeride areas), plutonism is dominantly granodioritic and exhibits the same structural features: NW-SE maximum stretching and overturning to the SE. Middle Carboniferous (Namurian-Westphalian) extension was parallel to the Variscan belt both in the Massif Central and southern Armorican area. This extensional regime was active from the late Visean in the north, while compression dominated in the southernmost domains (Montagne Noire and Pyrenées). The second extensional stage occurred from Late Carboniferous to Early Permian. This event was responsible for the opening of intramontane coal basins, brittle deformation in the upper crust, and ductile normal faulting localized on the margin of cordierite granite-migmatite domes. Data from the coal basins show that the half-graben is the dominant structural style, except for basins located along submeridianal left-lateral faults which have pull-apart geometries. Late Carboniferous extension occurred along the NE-SW direction. The NE-SW maximum stretching direction can be found in the whole Massif Central but is more developed in the eastern part. The extensional direction is transverse to the general trend of the belt, and top-to-the-NE shearing is dominant. Correlations of these two extension directions with neighboring Variscan massifs are discussed

Effets d'annonces de tapering par la Fed sur les pays d'Afrique du Nord et MENA et leur intégration au sein du système financier international

The first purpose of this thesis is to assess the impact of tapering’s announcement by the Fed during the period 2013 / 2015, and the impact these announcements had on assets prices in North Africa and more generally in MENA and African countries with the most developped financial sectors. We will assess, by studying the relevant events, the vulnerability of those countries to the shock in the international monetary policy sequence; consequently enabling a characterization of its impact, even on countries with relatively lowly developped financial markets. The second purpose of this thesis is to investigate the position of these countries within a large sample of MENA economies, and the remainder of the international financial system using a topological network. This enables to outline the interactions that bind those countries with each other, and also with the rest of the network —financial markets of advanced economies and other emerging economies. This thesis tackles a scarcely covered theme within the existing literature for the selected countries and also sheds new light on the question of financial integration using an atypical methodology.Cette thèse se consacre dans un premier temps à la compréhension des effets d’annonces de tapering réalisées par la Fed durant la période 2013-2015 et l’impact que ces annonces ont eu sur les pays d’Afrique du Nord et plus généralement des pays de la zone MENA et Afrique possédant des marchés financiers. Cela permet d’ainsi d’évaluer la sensibilité de ces pays aux chocs de politiques monétaires internationales, et permet ainsi de voir l’impact que cela a même sur des pays ayant de petits marchés financiers.Dans un second temps, cette thèse s’attache à estimer la place des pays de cette zone et de leur intégration au sein du système financier international à l’aide d’une topologie de réseau. Cela permet ainsi de voir les interactions, ou plutôt les connexions qui lient les pays de cette zone à l’intérieur même de celle-ci entre eux, et aussi avec le reste du réseau. Cette thèse permet d’étudier une thématique oubliée de la littérature au niveau des pays sélectionnés et dans un second temps, apporte un éclairage intéressant sur la question de l’intégration financière à l’aide d’une méthodologie atypique
